Addition of perfluoro-tert-butyl alcohol to a toluene solution of
alkene and cyclopropyl malonoyl peroxide increases the rate of dihydroxylation
product formation and the stereoselectivity observed, providing a simple and
effective method for acceleration of this important class of reaction. Basic
hydrolysis of the crude reaction mixture provides access to syn-diols in
high yield and stereoselectivity.

The use of nonanebis(peroxoic acid) enables a regio- and chemoselective
oxidation of aromatic amines hindered with an ortho substituent to the
corresponding nitro compounds, except for anilines ortho-substituted with
amino groups (NH2, NHR) or hydroxyl groups, where H-bonding between
an hydrogen of the adjacent group and an oxygen atom from the diperoxy acid
directs the oxidation.

The oxidation of malononitrile derivatives with peracid in methanol proceeds
with loss of the cyano groups to yield methyl esters in high yield. The method
was applied to a variety of malononitrile derivatives, some of which were
prepared by Pd- or Ir-catalyzed asymmetric allylic substitution.
